Description

Technical Field

[0001] This utility model relates to the field of automated welding fixtures for preventing welding slag spatter, and more particularly to an automated welding fixture for preventing welding slag spatter. Background Technology

[0002] Welding fixtures are used to ensure the size of the weldment, improve assembly accuracy and efficiency, and prevent welding deformation.

[0003] The inventors discovered during routine use of welding fixtures that welding slag would fly during welding, which meant that operators usually wore long sleeves and trousers and protective masks when welding. If the weather was hot, the operators would feel uncomfortable due to the thick clothing, which would affect the success rate of welding and thus cause problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated welding fixture that prevents welding slag from splashing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated welding fixture for preventing welding slag spatter, comprising a base plate, a fixing block fixedly connected to the top of the base plate, a screw threadedly connected to the inside of the fixing block, a pressing block rotatably connected to one end of the screw, a fixing plate fixedly connected to the top of the base plate, a protective device provided on the side of the base plate, a stabilizing device provided on the side of the pressing block, the protective device comprising a protective frame provided on the side of the welding clamp, a welding window provided on the side of the protective frame, a groove provided on the side of the protective frame, a protrusion fixedly connected to the other side of the protective frame, and a retaining ring fixedly connected to the surface of the protrusion, the retaining ring being a rubber ring.

[0006] The aforementioned components achieve the following effects: the retaining ring allows the protective frame to snap together, thus covering the welding fixture and preventing welding slag from splattering during welding. The welding window allows the operator to weld parts by simply wearing gloves and holding a welding torch inside the window. When the fixture is needed, one side of the rectangular part is brought into contact with the fixing plate, and the operator turns the screw by hand, causing one side of the pressing block to press against the other end of the rectangular part, thereby clamping the part onto the surface of the fixture. Since the fixture only requires one operator to operate, automation is achieved.

[0007] Preferably, a gasket is fixedly connected to the side of the protective frame, and the gasket is a rubber airbag.

[0008] The effect achieved by the above components is that, under the action of the gasket, there will be no rigid contact when the protective frame is snapped together.

[0009] Preferably, a locking rod is inserted into the side of the protective frame, and one end of the locking rod is inserted into the interior of the protrusion.

[0010] The effect achieved by the above components is that, under the action of the clamping rod, the protective frame can be fixed together to form a protective cover, thereby avoiding the phenomenon of welding slag splattering.

[0011] Preferably, a spring is fitted onto the surface of the lever, and the two ends of the spring are fixedly connected to one end of the lever on the side of the protective frame.

[0012] The aforementioned components achieve the following effects: Under the elastic potential energy of the spring, the clamping rod will not easily slip out of the protrusion. When welding parts, the parts are clamped on the surface of the fixture, the protective frame is moved relative to it, and the fixture is then placed inside the protective frame. The welding torch is placed inside the protective frame, the clamping rod is pulled outward, and the protrusion is inserted into the groove. Under the action of the retaining ring, the protective frame can be locked together, thus covering the welding fixture and preventing welding slag from splashing during welding. After the protrusion is fully inserted into the groove, the force of pulling the clamping rod is released, allowing the clamping rod to be inserted into the protrusion and fixed under the elastic potential energy of the spring. After protection is in place, the operator, wearing gloves, reaches into the protective frame through the welding window and holds the welding torch to weld the parts. During the welding process, the splashing welding slag is blocked by the protective frame, thus avoiding the phenomenon of welding slag splashing.

[0013] Preferably, the stabilizing device includes a rectangular groove formed on the side of the extrusion block, an arc-shaped clamp is rotatably connected to the inner wall of the rectangular groove, and a pull rope is detachably connected to the side of the arc-shaped clamp.

[0014] The effect achieved by the above components is that, under the action of the pull rope, the arc-shaped clamp plate rotates, thereby holding the round part to be welded and thus stabilizing the part.

[0015] Preferably, a retaining strip is fixedly connected to the inner wall of the rectangular groove, and the arc-shaped clamp is disposed between the retaining strip and the rectangular groove.

[0016] The effect achieved by the above components is that, under the action of the clamping strip, the arc-shaped clamping plate can be locked inside the rectangular slot when not in use, thus not affecting the clamping of parts of other shapes.

[0017] Preferably, rubber strips are fixedly connected to the side of the arc-shaped clamp, and the rubber strips are evenly arranged on the side of the arc-shaped clamp.

[0018] The effect achieved by the above components is that, under the action of the rubber strip, the friction on the surface of the arc-shaped clamp increases, thereby preventing the parts from rotating.

[0019] Preferably, an arc-shaped plate is fixedly connected to the side of the fixing plate, and the arc-shaped plate is an elastic rubber plate.

[0020] The aforementioned components achieve the following effects: The curved plate provides some obstruction to the circular part, preventing it from directly contacting the edges of the fixed plate and thus avoiding deformation due to pressure. When clamping and welding the circular part, it is placed between the fixed plates. The screw is turned by hand, causing the pressing block to move towards the surface of the part, clamping it between the pressing block and the fixed plate. The curved plate again provides some obstruction, preventing direct contact with the edges of the fixed plate and avoiding deformation. The curved clamp is then pulled out from the rectangular groove, and the pull rope is connected to it. When the part contacts the pull rope, the curved clamp holds the surface of the part. The rubber strip increases the friction on the surface of the curved clamp, preventing the part from rotating and achieving a stable position.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a protective device, when welding parts is required, the parts are clamped on the surface of the fixture, and the protective frame is moved relative to the fixture, so that the fixture is covered inside the protective frame. The welding torch is placed inside the protective frame, the locking rod is pulled outward, and the protrusion is inserted into the groove. Under the action of the locking ring, the protective frame can be locked together, thus covering the welding fixture, thereby preventing the phenomenon of welding slag splattering during welding. After the protrusion is fully inserted into the groove, the force of pulling the locking rod is released, so that the locking rod is inserted into the protrusion for fixation under the elastic potential energy of the spring. After the protection is in place, the operator, wearing gloves, reaches into the protective frame through the welding window and holds the welding torch to weld the parts. During the welding process, the splattering welding slag is blocked by the protective frame, thus avoiding the phenomenon of welding slag splattering. This solves the problem that the operator needs to wear long clothes and trousers to weld due to the welding slag splattering. Attached Figure Description

[0027] Example 1, as Figure 1-3 As shown, an automated welding fixture for preventing welding slag spatter includes a base plate 1, a fixing block fixedly connected to the top of the base plate 1, a screw 5 internally threaded to the fixing block, a pressing block 4 rotatably connected to one end of the screw 5, a fixing plate fixedly connected to the top of the base plate 1, a protective device 2 provided on the side of the base plate 1, and a stabilizing device 3 provided on the side of the pressing block 4. When the fixture is needed, one side of the rectangular part is brought into contact with the fixing plate, and the operator manually turns the screw 5 so that one side of the pressing block 4 presses into contact with the other end of the rectangular part, thereby clamping the part on the surface of the fixture. Since the fixture only requires one operator to operate, automation is achieved.

[0028] Reference Figure 2The protective device 2 includes a protective frame 21 disposed on the side of the welding clamp. A welding window 25 is provided on the side of the protective frame 21, and a groove is provided on the side of the protective frame 21. A protrusion 22 is fixedly connected to the side of another protective frame 21, and a retaining ring 23, which is a rubber ring, is fixedly connected to the surface of the protrusion 22. Under the action of the retaining ring 23, the protective frames 21 can be locked together, thus covering the welding clamp and preventing welding slag from flying during welding. The welding window 25 allows the operator to wear gloves and hold the welding torch inside the welding window 25 to weld parts. When using the fixture, one side of the rectangular part contacts the fixed plate, and the operator manually turns the screw 5, causing one side of the pressing block 4 to press against the other end of the rectangular part, thus clamping the part onto the surface of the fixture. Since the fixture only requires one operator, automation is achieved. A washer 24, a rubber airbag, is fixedly connected to the side of the protective frame 21. The washer 24 prevents rigid contact when the protective frame 21 is engaged. A locking rod 26 is inserted into the side of the protective frame 21, with one end inserted into the protrusion 22. The locking rod 26... The protective frame 21 can be fixedly engaged to form a protective cover, thus preventing welding slag from splashing. A spring 27 is fitted on the surface of the clamping rod 26. The two ends of the spring 27 are fixedly connected to the side of the protective frame 21 and one end of the clamping rod 26, respectively. Under the elastic potential energy of the spring 27, the clamping rod 26 will not easily slip out of the protrusion 22. When welding parts is required, the parts are clamped on the surface of the fixture, the protective frame 21 is moved relative to it, so that the fixture covers the inside of the protective frame 21. The welding torch is placed inside the protective frame 21, the clamping rod 26 is pulled outward, and the protrusion 22 is removed. Inserted into the groove, the protective frame 21 can be locked together by the retaining ring 23, thus covering the welding fixture and preventing welding slag from splashing during welding. After the protrusion 22 is fully inserted into the groove, the force of pulling the retaining rod 26 is released, allowing the retaining rod 26 to be inserted into the protrusion 22 for fixation under the elastic potential energy of the spring 27. After protection is in place, the operator, wearing gloves, reaches into the protective frame 21 through the welding window 25 and uses a welding torch to weld the parts. During the welding process, the splashing welding slag is blocked by the protective frame 21, thus avoiding the phenomenon of welding slag splashing.

[0029] Reference Figure 3The stabilizing device 3 includes a rectangular groove 31 formed on the side of the extrusion block 4. An arc-shaped clamping plate 32 is rotatably connected to the inner wall of the rectangular groove 31. A pull rope 33 is detachably connected to the side of the arc-shaped clamping plate 32. Under the action of the pull rope 33, the arc-shaped clamping plate 32 rotates, thereby holding the circular part to be welded, thus stabilizing the part. A retaining strip 34 is fixedly connected to the inner wall of the rectangular groove 31. The arc-shaped clamping plate 32 is positioned between the retaining strip 34 and the rectangular groove 31. Under the action of the curved clamping plate 32, it can be locked inside the rectangular groove 31 when not in use, thus not affecting the clamping of parts of other shapes. Rubber strips 36 are fixedly connected to the side of the curved clamping plate 32. The rubber strips 36 are evenly arranged on the side of the curved clamping plate 32. Under the action of the rubber strips 36, the friction on the surface of the curved clamping plate 32 increases, thus preventing the parts from rotating. An curved plate 35, which is an elastic rubber plate, is fixedly connected to the side of the fixing plate. Under the action of the curved plate 35, the circular part is somewhat blocked, thus preventing the part from directly contacting the edges of the fixed plate and being squeezed and deformed by the edges of the fixed plate. When it is necessary to clamp and weld the circular part, place the circular part between the fixed plates, turn the screw 5 by hand to move the extrusion block 4 toward the surface of the part, so that the part is clamped in the gap between the extrusion block 4 and the fixed plate. Under the action of the curved plate 35, the circular part is somewhat blocked, thus preventing the part from directly contacting the edges of the fixed plate and being squeezed and deformed by the edges of the fixed plate. Pull the curved clamp 32 out from the inside of the rectangular groove 31, and connect the pull rope 33 to the curved clamp 32. When the part comes into contact with the pull rope 33, the curved clamp 32 can hold the surface of the part. Under the action of the rubber strip 36, the friction of the surface of the curved clamp 32 increases, thus preventing the part from rotating and achieving a stabilizing effect.

[0030] Working principle: When using an automated welding fixture to prevent welding slag spatter, the rectangular part is placed in contact with the fixed plate. The operator manually turns the screw 5, causing one side of the pressing block 4 to press against the other end of the rectangular part, thus clamping the part onto the surface of the fixture. Since only one operator is needed, automation is achieved. When welding, the part is clamped onto the surface of the fixture, and the protective frame 21 is moved relative to it, so that the fixture covers the inside of the protective frame 21. The welding torch is placed inside the protective frame 21, and the locking rod 26 is pulled outward, inserting the protrusion 22 into the groove. Under the action of the retaining ring 23, the protective frame 21 can be locked together, thus covering the welding fixture and preventing welding slag spatter during welding. After the protrusion 22 is fully inserted into the groove, the force of pulling the locking rod 26 is released, allowing the locking rod 26 to be inserted into the protrusion 22 for fixation under the elastic potential energy of the spring 27, thus protecting the part. Afterwards, the operator, wearing gloves, reaches into the protective frame 21 through the welding window 25 and uses a welding torch to weld the parts. During the welding process, the spatter is blocked by the protective frame 21, thus preventing the spatter from flying. When it is necessary to clamp and weld a round part, the round part is placed between the fixed plates, and the screw 5 is turned by hand to move the extrusion block 4 toward the surface of the part, so that the part is clamped in the gap between the extrusion block 4 and the fixed plate. Under the action of the arc plate 35, the round part is blocked to a certain extent, so that the part does not directly contact the edge of the fixed plate, and thus does not deform due to the edge of the fixed plate. The arc clamp 32 is pulled out from the inside of the rectangular groove 31, and the pull rope 33 is connected to the arc clamp 32. When the part comes into contact with the pull rope 33, the arc clamp 32 can hold the surface of the part. Under the action of the rubber strip 36, the friction of the surface of the arc clamp 32 increases, so that the part does not rotate, thus achieving a stabilizing effect.
